We list the following latest developments in nonlinear inversion of seistnictrace:. Improved inversion algorithms,including the obtainment of analytic formulafor estimating Jacobi matrix.. Discovering the advantage of nonlinear inversion,and the distinction betweenlinear inversion and nonlinear inversion when they are used in solving special prob-lem etc.. Researches on the method for improving resolution in nonlinear iteration,and discovering the regularity of how iterative output sequence becomes chaotic.. In order to apply nonlinear inversion in reservoir search,people have accom-plished various numerical experiments and applied the experimental results in realreservoir search,receiving satisfactory effect.
